"What We Do in the Shadows" is a mockumentary-style comedy about the lives of vampires. It was originally a 2014 movie that followed the mundane lives of vampires living in a small town in New Zealand. The TV show, which premiered in 2019, follows three new vampires that are introduced to the "What We Do in the Shadows" world, along with their familiar and a new type of vampire called Colin Robinson.

While both the movie and the TV show have a particular deadpan comedic tone intertwined throughout their entirety, the show feels like a natural successor to the film. The TV show is improvised, which allows it to establish a specific comedic tone, although different actors do the improvisation. The show has multiple female lead characters, which is one of the key differences from the movie.

According to Peter Foy of CBR, the show adaptation "outdoes its source material proving it was better suited for the television medium, to begin with". The show has more flexibility and exploration than the movie, and it builds on everything the movie established, fleshing out a new group of vampires. The TV show has even become more popular than the movie, and it has officially been renewed for Season 3 on FX.

In summary, the TV show is a natural successor to the movie, and it has more flexibility and exploration than the movie. The show has multiple female lead characters, and it has become more popular than the movie.
